‐ CAUTION ‐
Westell recommends that two people be used to replace the
heat exchanger, one to hold the exchanger box on the outside
of the door, and one to remove/attach hardware on the inside
of the door.
1.
Open door, unplug power cord.
Open the Boxer‐30 door,
and unplug the heat exchanger's power cord from the AC
outlet box inside the Boxer‐30.
2.
Detach and set aside the four bottom bolts.
On the inside
of the door are 4 bolts that secure the bottom part of the
heat exchanger box to the door. Remove the four bottom
bolts, see Figure 20 for the location of the bolts.
3.
Detach and set aside the two top nuts
. On the inside of the
door are 2 nuts that secure the top part of the heat ex
changer to the door. While another person on the exterior
side of the door holds the exchanger box, remove the two
top nuts. Keep the nuts for the new unit.
4.
Lift exchanger box off the door.
From the exterior side of
the door, lift and pull off the heat exchanger box from the
door, allowing the two top bolts to exit out the top holes
and feeding the power cord out the hole provided for it at
the top right inside corner of the door. Set aside the unit
being replaced.
5.
Open and inspect the replacement unit.
Open the shipping
box for the new heat exchanger, examine the unit for any
shipping damages. If no damage is present, the new unit
may be mounted.
6.
Lift new unit and feed power cord through the hole.
With
one person on each side of the opened door, lift the heat
exchanger. Feed the AC power cord through the hole
provided for it at the top right
inside
corner of the door.
7.
Hang unit from top two holes.
Align the two protruding
bolts on the back side of the exchanger with the two top
holes on the door which were vacated by removing the old
exchanger. Verify the AC cord is hanging freely on the in
side of the door. Insert the two top bolts through the top
